Known as one of the most prolific and decorated defensive backs ever to play the game, Walls is the only 3 time leader in interceptions in NFL history. Under the tutelage of Eddie Robinson, Tom Landry, Bill Parcells and Bill Belichick, Walls has learned life lessons on and off the field from some of the all-time greatest coaches. In March of 2007, Everson donated a kidney to former teammate and friend Ron Springs who has diabetes.
